This study focused on programs to promote breastfeeding in order to prevent early weaning of working mothers' infant children. A non-randomized intervention study was conducted using a survey of mothers who had returned to work after childbirth, including both participants and non-participants in a program to promote breastfeeding. The sample consisted of 200 mothers of infants ranging from 6 to 10 months of age. Factors associated with early weaning were analyzed with the chi-square and Fisher's exact tests and multiple logistic regression (α = 0.05). The results showed statistical differences between the groups in relation to exclusive breastfeeding (p < 0.0001) and breastfeeding (p < 0.0001). There was a statistically significant difference (p = 0.0056) between the groups in relation to time between childbirth and return to work. There was no difference between the end of maternity leave and weaning time. Mothers that were unable to nurse their infants during the work shift showed 4.98 times higher odds (95%CI: 1.27-19.61) of weaning them before the fourth month of age.
本研究聚焦于促进母乳喂养的项目，以防止职业母亲的婴幼儿过早断奶。采用对产后重返工作岗位的母亲进行调查的方式开展了一项非随机干预研究，调查对象包括参与和未参与促进母乳喂养项目的母亲。样本由200名婴儿年龄在6至10个月的母亲组成。采用卡方检验、费舍尔精确检验和多元逻辑回归分析（α = 0.05）与过早断奶相关的因素。结果显示，两组在纯母乳喂养（p < 0.0001）和母乳喂养（p < 0.0001）方面存在统计学差异。两组在分娩至重返工作岗位的时间方面存在统计学显著差异（p = 0.0056）。产假结束时间和断奶时间之间没有差异。在工作班次期间无法哺乳婴儿的母亲，在婴儿4个月龄前断奶的几率高4.98倍（95%置信区间：1.27 - 19.61）。
